Monitorama 2018 Talks

Hi I'm Ilan, I work at Datadog, a monitoring and analytics platform for large-scale applications and infrastructure. I've been at Monitorama this week and figured I'd make it easy to find the talks from the conference.

Installing Docker (Virtualbox, boot2docker, docker)

Download and install the latest boot2docker for OS X.
Open a new Terminal and enter boot2docker init
Run boot2docker start
You will be given an environment variable to export export DOCKER_HOST=tcp://192.168.59.103:2375. Add that to your bash_profile or equivalent.
